Express in polar form the complex expressions below $($show your steps, not just a result

and express the final result for the phase angle in radians$).$

Hint: when determining the polar angle, calculators may give you by default the result for the arctangent

defined over two quadrants, with the computer implementation of ATAN $($between $-/2$ and $/2)$ while in

general cases you need the arctangent over four quadrants, which corresponds to the computer

implementation of ATAN$2($between $-$ and $).$ If you use a standard calculator, you may select th
